dc.description.abstract | Activation of dendritic cells (DCs) by viruses is critical for both innate and adaptive immune responses. In this report, we investigated the role of type I interferon (IFN) in the activation of DCs by respiratory syncytial virus (RSV). Using DCs from type I IFNR−/− mice, these studies indicate that maturation, including upregulation of co-stimulatory molecules and optimal cytokine production, by RSV infection was dependent on type I IFN receptor signaling. Subsequently, studies using DCs from wild type mice demonstrate that continued production of type I IFN during later stages of DC maturation could alter their activation profiles. IFN-α and IFN-β were upregulated in DCs grown from bone marrow of wild type mice after infection with RSV. In order to determine their function in competent DCs, blocking antibodies were used to specifically inhibit IFN-α/β . The data demonstrate that production of IFN-β, but not IFN-α, in RSV-infected wild type DCs promotes chemokine production and toll-like receptor (TLR) expression, while limiting IL-12 production. The inhibition of IL-12p70 by IFN-β correlated with suppressed IL-12p40 expression levels. Furthermore, the addition of recombinant IFN-β potently inhibited IL-12p40 expression in mature DC subsets during RSV infection, while only the highest dose of IFN-α had any inhibitory effect. Together, our studies provide insight into the complex regulation of DC maturation and IL-12 production co-ordinated by type I interferons in RSV-infected dendritic cells, and demonstrate that type I IFN has specific roles depending upon the stage of DC maturation. | en_US |
